Rail Welding (Aluminothermic / Thermite) SWMS
Aluminothermic rail welding — molten metal at >2,500°C, crucible safety, mould installation, post-weld grinding. RCS during grinding cycle. WTIA and AS 1085.20.
SWMS variants reference your state’s WHS legislation. Instant download after payment.
Aluminothermic (thermite) welding joins rail sections using a molten iron-aluminium reaction exceeding 2,500°C within a sand mould, followed by shearing and grinding. Work occurs in live rail corridors, triggering WHS Regulation 2025 HRCW provisions, Rail Safety National Law, and ONRSR network operator safety obligations.
Hazards identified
3 hazards covered, sorted by priority.
Severe burns, fatal blast injury
Silicosis, irreversible lung disease
Fatal struck-by, multiple casualties
Control measures
Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.
- 1Pre-heat moulds to eliminate moisture; verify crucible integrity and tap pin before ignition.
- 2On-track protection per ONRSR rules: lookout, absolute occupation, or track warning system.
- 3P2 RPE, on-tool extraction during grinding; FR clothing, face shield, spats during pour.
Applicable Codes of Practice
Mandatory weld procedure, qualification, and acceptance criteria
Hot work, fume, RCS, and PPE controls
High-Risk Construction Work triggered
Welding occurs within the rail corridor with train movements adjacent or under occupation.
Electrified networks expose workers to 1500V DC or 25kV AC overhead traction.
SWMS mandatory before work starts; non-compliance is a Category offence.
